Tests were conducted under idle and load states. The computer was left to sit after 30 minutes after being turned on to check the idle temperature. The load temperature was found by running the latest version of Prime95 which supports multi-core CPUs by default. Temperatures were obtained through SpeedFan. The chart below is ordered by lowest load temperatures.

Overall the AeroCool DCC-C900 had an idle temperature of 45C and a load temperature of 61C. These temperatures are below the average of all of the coolers that we have tested. This could have been due to it not being able to be installed properly. It’s hard to tell what the test results could have been if the cooler was able to be installed properly.
